More Detail

The display to the left is interactive and provides several ways to view the data.

Controlling this (right-hand) Window

To the right of the map towards the top are four buttons which control the contents of this window. The JOURNAL, BIOTA, and SITES buttons display selected journal entries, plants and animals originally described during the expedition, and campsites, respectively.

The Timeline

Immediately below the map is a timeline representing the time period November, 1805 to March, 1806. Click anywhere on the timeline and the progress along the trail will display. A small campfire on the map indicates where Lewis and Clark camped on that day. If journal entries are displayed in this window, the entry for the selected day will display, or if sites are displayed here, illustrations of the current campsite will display.

Immediately below the timeline are button controls for the timeline. The far left button resets time to November, 1805. The buttons with double arrows pointing left and right step back or forward one day, respectively. The far right button, single arrow, runs time forward automatically (like a VCR play button), and the center button, the square, will halt the automatic progression of depicted time.

Zooming in on the Map

To the right of the map towards the bottom is a compass rose indicating N, S, E, W. Below the compass rose are small magnifying glasses with a + and - in the center. If you move the cursor over the + or - and press the left mouse button and hold, the camera will zoom in or out, respectively. The small red crosshairs on the map indicate the location the camera is zooming to or from. If you move the cursor over the compass rose and press the left mouse button and hold, you can pan the camera north, south, east, or west. Note that you can't look beyond the edges of the map (which means that no panning is possible unless you are zoomed in).
